Cultural impact assessment system is a program to improve the quality of people`s life by minimizing the negative effects and maximizing the positive effects on the cultural environment when a central government or local governments implement policies or plans. It was introduced in 2013 by Framework Act on the Promotion of Cultural Industries. Now the Ministry of Culture, Sports and Tourism is promoting a pilot project for cultural impact assessment system to reduce trial and error and settle it as a successful system. This study examined previous studies, international case studies, and various cultural impact assessment systems in oder to successfully seated cultural impact assessment systems and proposed ways to improve evaluations regarding objects, index, process, scale of objects, and evaluation agency. For the system to run smoothly in the future, additional researches are needed on the scale of evaluation objects, setting up detailed evaluation index, the composition of evaluation committee and its operation, and the introduction of cultural impact evaluators.
